Emma Stetson Warrick - 1850 - Maine to Arkansas

Emma was my great-grandmother.She was born around 1850(my aunt is looking for exact date).Originally from Maine, but ended up in Crawford County, Arkansas married to my great-grandfather, John Warrick.We don't know anything about her family.If anyone out there has any information - it would be greatly appreciated.My aunt Em is 85 and asked me over the holidays to help her.Thank You!
